Application filed May as, 1925. Serial No. 33,544.

To all "whom it may concern:

Be it known that I, WINFRED L. SMITH, a citizen of the United States,residing at \Vestbrook, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in Adjustable ToolHeads; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention relates to hand tools and particularly to the rake and hoetype of tool and has for its object the provision of means by which therake or hoe head may be adjusted relatively to the handle to permitclose approach to the wall of a building or the side of a curb stone orcoping.

Another object of the invention is the provision of means by which theadjustment of the head may be expeditiously accomplished while the toolis in use and while it is in working position so that the proper p anglemay be readily accomplished to better perform the work and after thetool has been used with the head at an adjusted angle it may be returnedto its former position and the work continue without changing theposition of the handle.

The construction and operation and advantages of the invention will bedescribed in detail hereinafter and will be found illustrated in theaccompanying drawings in which- Figure 1 is a side view of the improvedtool showing it as a rake,

Figure 2, a top plan view showing the handle partly in section,

Figure 3, a sectional view on a plane indicated by the line 33 of Figure1,

Figure 4, a sectional view on a plane indicated by the line 4 4 ofFigure 1, and

Figure 5, a detail view of a hoe head arranged to housed on the toolhandle.

In the drawings, similar reference characters will be used to designatecorresponding parts throughout the several views.

The handle 1 of the improved tool is tubular as shown and has anextension 2 that is swivelly mounted thereon by means of ferrule 3secured to the extension 2 by means of a rivet 4c. 5 indicates a rodalso secured to extension 2 by means of the rivet-4 and extendingtihnough the'bore of the tubular 'eted, to the blade designated 20.

wardly and outwardly. The free ends of,

prongs 10 are pivotally secured to the tool head 11 by means of ears 12,the pivot pins 13 therefor being of a type that may be readily removedto permit quick changing of the tool head from one type to another.

1-1 indicates an arm extending from the tool head 11 intermediate of thecars 12 and having an upwardly curved portion that is pivotally securedto a rod 15 by means of a removable pin 16 of the same type as the ins13 heretofore referred to. Rod 15 extends through an opening in the ring9 into the interior of the sleeve 8 and has on its inner end a yoke 17the cross head 18 of which is threaded to engage the threads 6 on therod 5. v

It will be apparent that in using the tool the angle of the head 11 maybe quickly adjusted by turning the extension 2 relatively to the handle1, the threaded connection of the cross head 8 with the end of the rod 5moving the head 11 to change the angle of the head relatively to thehandle.

' In Figure 5 is shown a hoe head that is adapted for use with thehandle in which the ears 12 and the'arm 141: are shown riv- In theadaptation of the invention I have shown in Figures 1, 2, and 3, thecars 12 and arm 14 are cast on the head but obviously as indicated inFigure 5 these parts may be made separate and riveted to the tool headif so desired.

What is claimed is e- 1. In a tool, a handle, a head pivotally engagingsaid handle, an extension of the handle swivelly mounted thereon, a rodsecured to said extension and extending through the handle, another rodengaging the head, a yoke on the last mentioned rod, and threadedconnection between said yoke a he fir t mentioned r 2. In a tool, ahandle, prongs secured to other rod pivotally engaging said head, andand extending from one end of-the handle, a yoke on said rod and havinga threaded a head pivotally engaging said prongs an aperture engagingthe threads on the first 10 extension of the handle sWiVelly mountedmentioned rod. thereon, a rod secured to said extension and In testimonywhereof I aflix my signatransversely through said handle, the free ture.end of said rod being screw threaded, an- WINFRED L. SMITH.
